CHAlN-STOPPERf SPECIFICATION forming part of Letters Patent No. 677,188, dated June 25, 1901. Application filed Mai 8,1901. Serial No. 50,343. (Nomocleh) To all whom it may concern:-

Beit known that LMIcHEALALBEnrDREEs, a citizen of the United States, and a resident of Peshtigo, in the county of Marinette and State of lVisconsin, have invented a new and Improved Chain-Stopper, of which the following is a full, clear, and exact description.

This invention relates to a device for lockin g chains; and the object is to provide means for easily and effectively stopping the chain, which device may be readily released without danger to the operator, notwithstanding that the chain may be under great strain at all times.

The invention is useful in connection with all purposes for which chains are employed, as will be fully understood by persons skilled in the art.

This specification is a specific description of one form of the invention,while the claims are definitions of the actual scope thereof.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the views.

Figure 1 is a plan view of the invention. Fig. 2 is a section on the line 2 2 in Fig. 1, showing the chain stopped; and Fig. 3 is a like view showing the chain released.

The device comprises a body having a baseplate a, with holes a 'for fastening the plate to the surface on which the stopper is mounted. This base a has oppositely-arranged side lugs a each of which is formed with two openings a and 61 therein. The openings in the lugs to are respectively in transverse alinement with each other-that is to say, the open ing a of one lug is in transverse alinement with the opening a of the other lug and the same is true as to the openings a.

IVorking with the body is a stopper bar comprising two limbs 19 and b, arranged in parallelism and connected rigidly together by a member 71 at their outer ends. This member is preferably formed integrally with the bars I) and b and provided with an eye 11 to which may be connected a cord or the like 0 for permitting the stopper-bars to be drawn from the position shown in Fig. 2 to that shown in Fig. 3. The limb b of the stopper-bar is of approximately twice the length of limb b, so that when the stopper-bar is drawn to open position (see Fig. 3) the limb b will be moved out of the space between the lugs (0 hen the stopper-bar is moved to the locked position, (see Fig. 2,) both of the limbs will lie across the space between these 111 gs. Achain, cord, or other connection dis attached permanently to the limb l) of the stopper-bar and is provided with a key d at its end, which key may be removably placed in an opening in the end of the limb b to lock the stopperbar in the position shown in Fig. 2 When the stopper-bar is, moved into locked position, the limbs l7 and b straddle a link of the chain lying opposite the sides thereof, thus holding the chain fast in the stopper. hen the stopper-bar is moved to open position, the chain is free to run over the top of the long limb b of the stopper-bar. cord or ro'pe c and the chain d the stopperbar may be moved from one position to the other readily and without danger of the chain striking the operator.

Having thus described my invention, I claim as new and desire to secure by Letters Patent 1. A chain-stopper, comprising a body with lugs thereon between which a chain is arranged to run, and a stopper-bar slidable By means of the through said lugs to engage and holdthe chain. 7

2. A chain stopper, comprising a body adapted to have a chain run thereon, and a stopper-bar arranged to slide across the chain and engage between two links thereof to lock the same.

3. A chain-stopper, comprising a body adapted to have a chain run thereon, and a stopper-bar slidably mounted in the body and having two limbs arranged to straddle the chain.

4. A chain-stopper, comprising a body an ranged to have a chain run'thereon, and a stopper-bar comprising two parallel limbs mounted to slide in the body to straddle the chain, one of said limbs being shorter than the other limb, for the purpose specified.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.

MICHEAL ALBERT DREES.
